Definitions

  • the present invention pertains to screens which provide shade and/or save energy. More in particular, the invention pertains to fire retardant, drapable screens for use in conservatories or greenhouses, mainly screens that partially consist of thin and flexible plastic strips that can be converted into a large, flat and pliable product, such as a fabric, in particular by weaving, using one or more yarns, if necessary.
  • Such screens are frequently used for protecting plants, in the open field or indoors in greenhouses, for controlling the incoming and outgoing radiation energy to a certain extent, so that the plants are protected against too strong sunlight and against too high or too low temperatures.
  • Said screens also called curtains, are spread vertically and/or horizontally over very large areas, with areas of 30,000 m 2 not being exceptional. Because the plants to be protected may represent a great value, protecting them serves a major economic purpose.
  • opening and closing the screens is done by electric means, with the screens being moved to the active or inactive position by means of motors.
  • a fire may start, for example in the case of the electric defects, during repair work involving grinding or welding, or of vehicles moving under the screen in the greenhouse. It has been established that such fires can spread very quickly over large areas via the screens. The fires constitute a danger to personnel present in the greenhouses, and can be destructive to the greenhouse itself and also to its contents.
  • Such screens for greenhouses are disclosed, for example in EP 0 696 884 B1 , which discloses a screen comprising flexible strips consisting of a halogen- or phosphorus-containing plastic film, preferably made of PVC, PVDC, PCTFE, PVF, FEP, PTFE, E/TFE or PETP, which also comprises a UV stabiliser, at least partially laminated with a metal film and connected into a continuous product by crocheting or weaving, using a yarn system, said yarn system at least partially consisting of a flame retardant material, such as modacryl yarns.
  • the strips as well as the yarn system are at least partially made of materials which are flame retardant or not easily flammable.
  • WO 2011/096882 A1 discloses a greenhouse screen comprising strips that are connected with a yarn system by means of hosiery, knitting, warp-knitting or weaving process, wherein the screen comprises multilayer polyester strips having a thickness less than 60 ⁇ m and wherein at least one layer of the multilayer polyester strips is white and at least one layer is black.
  • WO 2013/117696 A1 discloses a flame retardant screen comprising strips having a thickness of at most 100 ⁇ m, which are connected by flame retardant yarns. Hardly any flame retardants are incorporated in the strips which are made of a plastic having a limiting oxygen index of at least 18%, contain at most 0.15 wt.% of Phosphorous, contain at most 900 ppm by weight of chlorine, fluorine or bromine, and contain at most 1.0 wt.% of Sulphur. The only mentioned type of polymer of the strips is polyester.
  • EP 2 457 436 A1 discloses a shading screen made from fire resistant halogen-free polymer films, optionally laminated with a metal film, wherein the halogen-free polymer is polycarbonate, polycarbonate-polysiloxane block-copolymer or a blend of polycarbonate and polysiloxane.
  • XLS OBSCURA REVOLUX A/B + B/B as sold by AB Ludvig Svensson, comprises two separate fabrics, wherein the top fabric comprises in machine direction tapes of PVC laminated with Aluminum foil warp-knitted together with transparent modacryl yarns and with fire retardant polyester yarns.
  • the lower fabric comprises in machine direction tapes black polyester tapes warp-knitted together with fire retardant polyester yarns.
  • WO2012/079243A1 discloses polyolefin based articles, such as tapes, fibers or sheets, having a fire retardant composition.
  • a screen comprising a top fabric and a bottom fabric, wherein the top fabric comprises halogen-containing polymeric strips and a light-reflective film or foil laminated to at least a portion of the halogen-containing polymeric strips and wherein the bottom fabric comprises polyolefin tapes, the polyolefin tapes comprising a synergistic fire resistance composition comprising a mixture of at least two chemical compounds, each chemical compound being selected from a phosphonate compound, a diphosphonate compound, or an alkyl- or arylphosphonic acid, and at least one 1,3,5-triazine compound, fulfils the requirements of the NTA 8825:2010 fire test.
  • the fabric used as bottom fabric in darkening screens comprising polyolefin tapes comprising a synergistic fire resistance composition comprising a mixture of at least two chemical compounds, each chemical compound being selected from a phosphonate compound, a di-phosphonate compound and/or an alkyl- or arylphosphonic acid, and at least one 1,3,5-triazine compound, enables that the darkening screen can fulfil the requirements of the NTA 8825:2010 fire test.
  • the top fabric of the screen will during normal use in a greenhouse be facing the roof of the greenhouse, while the bottom fabric will be facing the interior of the greenhouse, in particular the plants growing in the greenhouse.
  • the halogen-containing polymeric strips may be made from polyvinylchloride (PVC), polyvinylidene-chloride (PVDC), polychlortrifluorethylene (PCTFE), polyvinylfluoride (PVF), fluorinated ethylene propylene (FEP), which is a copolymer of hexafluorpropylene and tetrafluorethylene, polytetrafluorethylene (PTFE), ethylene-tetrafluorethylene (E/TFE), which is a copolymer of tetrafluorethylene and ethylene.
